A method for permanently coloring fruits (cherries) and vegetables using carmine and other anthraquinones, using mixtures of multivalent metal ions and acid. The cherries are infused with a mixture of calcium ions, other multivalent metal ions, and carmine dye, at a pH at which the carmine is in soluble form. The cherries are then infused with an acidification solution which results in the precipitation of an insoluble carmine-metal ion complex within the cherries. Unused dye is treated and recycled.
